Excessive alarm monitor warnings after upgrade to WAS 70.0.25

If you upgraded to WAS 7.0.0.25 , regardless of your Portal version, you may notice a lot of otherwise innocuous alarm monitor threads warning along with various call stack such as below

AlarmThreadMo W UTLS0008W: The return of alarm thread "Non-deferrable
Alarm : 1" (0000001f) to the alarm thread pool has been delayed for
40968 milliseconds. This may be preventing normal alarm function within
the application server. The alarm listener stack trace is as follows:
<TRUNCATED>

WebSphere Application Server 7.0.0.25 introduced new serviceability
feature to enhance the monitoring/configurability of Alarm threads.
However the various settings introduced have default values that are
rather low and too low for Portal operations . One of the parameters is

com.ibm.websphere.alarmthreadmonitor.threshold.millis

which determines how long an alarm thread runs before the warning
is issued. So, for example, if the default settings value of
com.ibm.websphere.alarmthreadmonitor.threshold.millis is used then the
warning and possible stack traces are generated if the alarm threads
runs for more than 40 secs

The default is 40 secs which is very low for most of the portal activities.
